MailClient.Delete Method

Marks the specified email as deleted.

[Visual Basic]
Public Sub Delete( _
    info As MailInfo
)

[C#]
public void Delete(
    MailInfo info
);

[C++]
public: void Delete(
    MailInfo* info
);

[JScript]
public function Delete( 
    info: MailInfo
);

Parameters

info
The MailInfo instance to delete.

Remarks

Delete method only marks the email as deleted, only the MailClient.Quit method (POP3 and IMAP4) or MailClient.Expunge method(IMAP4 only) pures the deleted email from server. For POP3, deleted flag will lose if the connection is closed; FOR IMAP4, the deleted flag is permant even the connection is closed.

Example

[Visual Basic, C#, C++] The following example demonstrates how to receive email with EAGetMail POP3 & IMAP Component, but it doesn't demonstrates the events and mail parsing usage. To get the full samples of EAGetMail, please refer to Samples section.
